# BcMath\Number::divmod

(PHP 8 >= 8.4.0)

BcMath\Number::divmod — Gets the quotient and modulus of an arbitrary precision number

### Beschreibung

public BcMath\Number::divmod(BcMath\Number|string|int `$num`, ?int `$scale` = `null`): array

Gets the quotient and remainder of dividing $this by `num`.

### Parameter-Liste

`num`
  The divisor.
`scale`
  BcMath\Number::scale explicitly specified for calculation results. If `null`, the BcMath\Number::scale of the calculation result will be set automatically.

### Rückgabewerte

Returns an indexed array where the first element is the quotient as a new BcMath\Number object and the second element is the remainder as a new BcMath\Number object.

The quotient is always an integer value, so BcMath\Number::scale of the quotient will always be `0`, regardless of whether explicitly specify `scale`.

If `scale` is explicitly specified, BcMath\Number::scale of the remainder will be the specified value. When the BcMath\Number::scale of the result's remainder object is automatically set, the greater BcMath\Number::scale of the two numbers used for modulus operation is used.

That is, if the BcMath\Number::scales of two values are `2` and `5` respectively, the BcMath\Number::scale of the remainder will be `5`.

### Fehler/Exceptions

This method throws a ValueError in the following cases:

- `num` is string and not a well-formed BCMath numeric string
- `scale` is outside the valid range

This method throws a DivisionByZeroError exception if `num` is `0`.

### Beispiele

Beispiel #1 BcMath\Number::divmod() example when `scale` is not specified

`<?php
echo '8.3 / 2.22' . PHP_EOL;
[$quot, $rem] = new BcMath\Number('8')->divmod(new BcMath\Number('2.22'));
var_dump($quot, $rem);
echo PHP_EOL . '8.3 / 8.3' . PHP_EOL;
[$quot, $rem] = new BcMath\Number('8.3')->divmod('8.3');
var_dump($quot, $rem);
echo PHP_EOL . '10 / -3' . PHP_EOL;
[$quot, $rem] = new BcMath\Number('10')->divmod(-3);
var_dump($quot, $rem);
?>`

Das oben gezeigte Beispiel erzeugt folgende Ausgabe:

    8.3 / 2.22
    object(BcMath\Number)#3 (2) {
      ["value"]=>
      string(1) "3"
      ["scale"]=>
      int(0)
    }
    object(BcMath\Number)#4 (2) {
      ["value"]=>
      string(4) "1.34"
      ["scale"]=>
      int(2)
    }

    8.3 / 8.3
    object(BcMath\Number)#2 (2) {
      ["value"]=>
      string(1) "1"
      ["scale"]=>
      int(0)
    }
    object(BcMath\Number)#5 (2) {
      ["value"]=>
      string(3) "0.0"
      ["scale"]=>
      int(1)
    }

    10 / -3
    object(BcMath\Number)#3 (2) {
      ["value"]=>
      string(2) "-3"
      ["scale"]=>
      int(0)
    }
    object(BcMath\Number)#1 (2) {
      ["value"]=>
      string(1) "1"
      ["scale"]=>
      int(0)
    }

Beispiel #2 BcMath\Number::divmod() example of explicitly specifying `scale`

`<?php
echo '8.3 / 2.22' . PHP_EOL;
[$quot, $rem] = new BcMath\Number('8')->divmod(new BcMath\Number('2.22'), 1);
var_dump($quot, $rem);
echo PHP_EOL . '8.3 / 8.3' . PHP_EOL;
[$quot, $rem] = new BcMath\Number('8.3')->divmod('8.3', 4);
var_dump($quot, $rem);
echo PHP_EOL . '10 / -3' . PHP_EOL;
[$quot, $rem] = new BcMath\Number('10')->divmod(-3, 5);
var_dump($quot, $rem);
?>`

Das oben gezeigte Beispiel erzeugt folgende Ausgabe:

    8.3 / 2.22
    object(BcMath\Number)#3 (2) {
      ["value"]=>
      string(1) "3"
      ["scale"]=>
      int(0)
    }
    object(BcMath\Number)#4 (2) {
      ["value"]=>
      string(3) "1.3"
      ["scale"]=>
      int(1)
    }

    8.3 / 8.3
    object(BcMath\Number)#2 (2) {
      ["value"]=>
      string(1) "1"
      ["scale"]=>
      int(0)
    }
    object(BcMath\Number)#5 (2) {
      ["value"]=>
      string(6) "0.0000"
      ["scale"]=>
      int(4)
    }

    10 / -3
    object(BcMath\Number)#3 (2) {
      ["value"]=>
      string(2) "-3"
      ["scale"]=>
      int(0)
    }
    object(BcMath\Number)#1 (2) {
      ["value"]=>
      string(7) "1.00000"
      ["scale"]=>
      int(5)
    }
